Unfortunately wasn't able to progress past this point. Putting in the code didn't do anything no matter how much I tried. The story behind the game is interesting; dealing with grief and survivor's guilt is hard. Good job (ᵔᴥᵔ)
That's cuz that's the code for room 4's monitor-
You're in room 2, so the code would be 12321, thanks for playing the game tho :D
